Some more fun things: some Extras (mooks) can come in units for more efficient activation purposes. Units don't cost any extra beyond having must-buy unit requirements. Vehicles also exist, and they need to be operated by someone. However, a vehicle activate for a single plot point, which allows every passenger to shoot for free. This allows for some very efficient shooting activations, even if you risk losing the dismounts if they're still in the vehicle when it blows up.
